Return a scalar, matrix or N-dimensional array whose elements are all eps, the machine precision.
eps is the relative spacing between any two adjacent
numbers in the machine’s floating point system. This number is obviously
system dependent. On machines that support IEEE floating point arithmetic,
eps is approximately
2.2204e-16 for double precision and 1.1921e-07
for single precision.
When called with no arguments, return a scalar with the value
Given a single argument x, return the distance between x and the next largest value.
When called with more than one argument the first two arguments are taken as
the number of rows and columns and any further arguments specify additional
matrix dimensions. The optional argument class specifies the return
type and may be either
